Please Call For Price.
Accuphase P-7500 – We only stock brands that we love at HFL so it was a pleasant surprise when I had an opportunity to listen to the Accuphase P-7500 and instantly I was smitten, I have to say I was almost won over by the looks before it had even created a singe note, the presentation sounds just right though, honest but with a tad of warmth giving a very natural sound so if you are looking for a new amp, pre or source feel free to get in touch to arrange a demo of Accuphase.
Accuphase P-7500
High output stereo power amplifier bursting with musical expression
The P-7500 is Accuphase flagship model Class AB stereo power amplifier that provides supreme driving performance. The power amplification stage uses a 10-parallel push-pull power transistor architecture, providing a rated output power of 300 W / 8 ohms that vastly exceeds that of conventional models. Boasting an impressive signal-to-noise ratio of 130 dB and a damping factor of 1,000, it can effortlessly drive massive speakers and create musical recreations overflowing with energy. The P-7500 brings out the best of any speaker, allowing you to enjoy never-before experienced soundscapes.
Groundbreaking technology
The P-7500 power amplifier uses state-of-the-art circuitry and the highest quality materials to achieve a perfect blend of refined responsiveness and groundbreaking technology.
Ample output power
The 10-parallel push-pull power transistor output stage produces linear output power of 300 W into 8 ohms or 600 W into 4 ohms, and a whopping 900 W into 2 ohms of maximum output power.
Ultra low noise performance
Ideal gain distribution and other sophisticated techniques improve noise level suppression by 11% over the previous model.
High damping factor
With a damping factor of 1,000, the speakers can be driven with full control over the counter-electromotive forces to get the most out of your speakers.
Balanced remote sensing
Balanced remote sensing improves damping factor + by feeding back the GND – at the same time as signal output from the speaker terminals.
